1.7.4 Configuring PPP In Dialer Profile Configuration Mode
In Dialer Profile configuration mode, if the local end needs to receive a n incoming call,
PPP authentication must be configured at the local physical interface so as to
determine which dial interface the incoming call in oriented to.
There are two PPP authentication modes: PAP authentication and CHAP
authentication. With different PPP authentication modes, the desired c onfiguration
commands and application modes are different, as detailed below:
The PPP configuration commands involved are:
z encapsulation ppp
z ppp authentication { pap | chap }
z ppp pap sent-username name password { 0 | 7 } password
z ppp chap host hostname
z user username password { 0 | 7 } password

I. Apply PAP authentication

With PAP name authentication mode, configuration must be performed according to
the following steps, in which name1 and pass1 can be replaced with specific character
strings selected by the users.
z Configure the remote user name of the local Dialer interface: dialer remote-name
name1
z Configure link layer protocol encapsulation of the local physical interface:
encapsulation ppp
z Configure PPP authentication mode: ppp authentication pap
z Configure the user name and password of the rem ote router: user name1
password 0 pass1
z Configure the user name and password sent by the local Dialer interface or the
physical interface directly enabling DDR during PAP authentication : ppp pap
sent-username name1 password 0 pass1
Example 1: apply serial port
1) Configure local router:
Quidway(config)# user remoteuser1 password 0 remotepass1
Quidway(config)# dialer-list 1 protocol ip permit
Quidway(config)# dialer-list 1 protocol ipx permit
Quidway(config)# interface dialer 0
